The new 32-spline mainshaft included with the JB Conversions Super-Short Slip Yoke Eliminator is a full 9 inches shorter than the factory shaft and can accommodate just about any driveshaft yoke or flange. The heavy-duty tailhousing is heat-treated to T-6 specs and features a thicker cross section than some other units on the market and includes a support boss for the oil pump. In short, it's about the best you can do.
